The main working principle is to achieve the suction and discharge of liquid through the rotational motion of the rotor. This type of pump does not have traditional suction and discharge valves, but relies on the rotation of the rotor inside the pump body to directly act on the liquid, and transports the liquid from the suction end to the discharge end through compression. Specifically:
A rotary pump consists of a stationary pump casing and a rotating rotor. During the rotation of the rotor, energy is directly applied to the liquid in the form of static pressure through the side in contact with the liquid, while leaving space on the other side to create low pressure, thereby allowing the liquid to be continuously drawn in. This design makes the rotary pump suitable for transporting liquids with high viscosity, lubricity, but without solid particles. one
The rotor of a rotary pump is usually composed of a pair of synchronously rotating rotors, which generate suction (vacuum degree) at the inlet during the rotation process, thereby sucking in the material to be conveyed. The two rotors divide the rotor chamber into several small spaces and operate in a specific order, so that the medium (material) is continuously transported out. two
Multiple fixed volume conveying units in the working chamber of the rotary pump achieve the purpose of conveying fluid through periodic conversion. The mechanical energy of the electric motor is directly converted into the pressure energy of the conveyed fluid through the pump. The flow rate of the pump depends on the change in the working chamber volume and its frequency of change per unit time, and is independent of the discharge pressure. three
The structure of the rotary pump is compact, with a small volume and positive displacement properties. Its flow rate does not change with changes in back pressure, making it suitable for applications that require continuous and stable flow delivery
